Leaders emphasize need to work together as Donald Trump vows ‘America first’

Global leaders responded to the inauguration of President Donald Trump with wishes for good, and in some cases improved, relations with the U.S.—amid concerns amplified by his inaugural pledge that, “from this day forward, it’s going to be only America first.”

Mr. Trump had indicated before Friday’s ceremony that he would rewrite many long-established U.S. policy positions, and a common thread in official reactions from around the world was a hope for healthy ties.
